So those Sears twins brought you back from the full size? Man, those Onan's look huge. Are the engines that big or are the tractors a little small? Great herd.

I've never seen a flywheel on a Onan but it's the shroud and the flywheel cover that makes it look huge. I am not sure if the flywheel is that round or not because Im a newbie to Onan engines. Opposing Horizontal Shaft Kohler/Briggs is the same size.

Congrats, Gumby on your find!

High gear on my SS16 is powerful with the Onan twins. I can sometime pop a wheelie. :) Happy gardening!

I have found out that I can pop wheelies with my SS16. I have done it mainly in 3rd/High Gear. The Onans are some tough engines IF they are running!

Just don't pop a wheelie liked I did with my GT18. I was driving it up the ramp on my trailer and it came over backward on me... pinned me in the seat... I couldn't even reach and shut the engine off. Fortunately my wife and daughter saw me, and came over to get it off... however it took them and a neighbor to do it... heavy beast they are...

Yeah the non runner has a electrical issue. I believe it needs a switch. The selenoid is not clicking when the key is turned. I took the selenoid off and tested it and it worked great then. Im thinking the switch is bad. I tried a few switches I had in the building but none of them seemed to work (made sure the letters were the same on the posts). I'll just have to buy a new switch because obviously the ones I tried is laying around my building for a reason.

I hooked the jump box to the starter and it turned over great. I only kept it on there for a second just to make sure the starter was working correctly. I got a mailbox full of parts today . I got a carb from my chipper shredder and a fuel pump for tiller. Those should be running today and after those are running I'll start messing with the sears again.

The Onans do take up alot of space under the Sears hood. The flywheel tin covers the starter, flywheel, and some of motor, still big engines either way.
